Ive got a question for anyone out there willing to answer: Ive had a 10 gallon tank set up for about 5 months now and I just recently desided to try aquaruim salt. So my question is when i preform water changes with my gravel vacuum does the gravel vacuum filter out the salt as well? I just moved my tank and took out the water by my gravel vacuum into buckets for easier lifting then put it back into the tank. So im wondering do i have to add more salt back in because it filters the salt out or does it not and im good for now? The salt did disinigrate into my water for a day before i moved the water/tank. Thanks!
